HENRY ARCH CROSS, OF BICKNELL, INDIANA.

FORGE.

Specification of Letters Patent. Patented Feb. 29, 1916.

Application filed May 24, 1915. Serial No. 30,073.

v To all whom it may concern:

Be it known that I, HENRY A. CRoss, a citizen of the United States, residing at Bicknell, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Forges; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in I forges, and more particularly to such a dewill be simple, efficient, and durable.

l/Vith this general object in view, the invention resides in certain novel features of construction and in unique combinations of parts hereinafter fully described and pointed out in the appended claims.

In describing the invention, I shall refer to the accompanying drawlngs wherein like reference characters designate correspond,

ing parts throughout the several views and wherein:

Figure 1 is a side elevation of a forge constructed in accordance with my invention; Fig. 2 is a top plan view thereof with the hood removed; Fig. 3 is a vertical section taken on the diametrically extending line 33 of Fig. 2; Fig. 4: is a detail vertical section taken at right angles to Fig. 3 and viewed along the line 4:l of Fig. 2; Fig. 5 is a fragmentary section showing more particularly the manner of fastening and bracing the bearing ring to be described, and Fig. 6 is a horizontal section as seen on the plane indicated by the line 6-6 of Fig. 1.

I11 these drawings which constitute a part of the application, the numeral 1 designates a base preferably though not necessarily formed of concrete or the like, this base being provided for the rigid support of a tubular upright post 2 preferably having a flange at its lower end through which suitable anchors are passed, said anchorsbeing embedded in the base 1.

The upper end of the post 2 receives there- ...in a flange 3 which depends from a bearing ring 8, this ring being secured in any preferred manner against rotation in respect to the post 2. The upper side of the ring 3 is provided with an annular groove receiving therein ball bearings i which are likewise received by such a groove formed in an additional bearing ring 5 supported by said ball bearings. The ring 5 surrounds and is secured to an annular flange 6 which depends from a. horizontally disposed ring 7, said flange 6 being continued below the ring 5 into the bearing ring 3, whereby lateral shifting of the ring 7 and its bearing ring 5 in respect to the ring 3 and post 2 is prevented.

Resting on the horizontally disposed ring 7, is the flat bottom 8 of the fire pan 9, the latter being of construction yet to be described, while resting on the bottom 8 and disposed directly above the ring 7 is an annular flange 10 projecting outwardly from the lower end of an upright tubular flue 11. The flange 10, the ring 7, and the portion of the bottom 8 therebetween, are provided at intervals spaced circumferentially around the same, with vertically alined openings receiving the threaded upper ends of vertically disposed stay bolts 12, nuts 13 being threaded on said ends in contact with the upper side of the flange 10, while additional nuts 13 are disposed thereon in contact with the lower side of the ring 7. The stay bolts 12 are necessary for reasons to become obvious as the description proceeds, and by securing the upper ends there of in the manner just described, said bolts are not only rigidly anchored, but they serve as means for retaining the flue 11, the bottom 8, and the ring 7 in rigid relation, this twofold function of the stay bolts being considered a rather important feature of the invention. The lower ends of the stay bolts 12 are likewise threaded and provided with nuts 14 which contact with the upper sides of the feet 15 of a plurality of radially disposed upwardly and outwardly inclining brace rods 15, the outer ends of these rods being secured by any preferred means to the bottom 8 as clearly disclosed in Fig. 1. The threaded lower ends of the stay bolts 12 project below the feet 15 through a horizontally disposed bearing ring 16, additional nuts 1 1 being threaded on said ends in contact with the under side of said ring, it being thus evident that in addition to the functions above given the stay bolts,

they serve as means for rigidly spacing the bearing ring 16 from the ring 7, and that they serve to anchor the inner ends of the brace rods 15.

In most cases, ball bearings or the like 17 are disposed between the inner edge of the bearing ring 16 and the lower end portion of the post 2, which is preferably thickened at this point for engagement with these bearings, while the aforesaid inner edge of the ring is provided with a continuous groove receiving said bearings.

From the preceding description, when taken in connection with the accompanying drawings, it will be evident that the pan 9 and the parts carried thereby will revolve freely in respect to the base 1 and the post 2, yet that the pan is effectively braced at all times, by the stay bolts 12, the bearing ring 16 carried by the lower ends thereof, and the brace rods 15 retaining said ring 16 concentric to the axis upon which the pan rotates; This rotation of the pan is essential for a reason yet to be set forth.

The pan 9 is shown as comprising the flat horizontally disposed bottom 8, and six upright sides 18 and 18, the former being of considerably greater length than the latter. The ends of all of the walls 18 and 18 are joined to each other either integrally or otherwise, and the upper edges of said walls are disposed in the same horizontal plane, an angle iron 19 being riveted or otherwise secured to said upper edges on the outer sides thereof, this angle iron serving not only as means for reinforcing the several walls, but facilitating the attachment of a hood yet to be described.

Radiating from the upright flue l1 and having their outer ends secured to the shorter walls 18*, is a. trio of vertically spaced upright portions 20, these portions dividing the pan 9 into three fire boxes 21 whose outer sides are constituted by the walls 18, while their ends are formed by those designated at 18 the flue 11 constituting the inner sides of said fire boxes. Spaced an appropriate distance above the bottom of each fire box 21, is a horizontally disposed perforated blow pipe 22, the several pipes being connected by Ts or other suitable joints to branch pipes 23 which radiate from the upper end of a blast pipe 23, the lower end of said pipe 23 having a telescopic engagement with an upright rigid blast pipe 24 whichenters one side of the base 1 and rises within the tubular post 2,

whereby a blast of air forced into the pipe 24, will be evenly distributed to the several blow pipes 22 through the branches 23". Gate valves or the like 25, however, are preferably provided between the ends of the branches 23?, said gate valves being equipped with operating levers 24 disposed beneath the pan 9, wherebythe amount of air forced through the several branches to the blow pipes 22 may be under strict control of the operator.

The opposite ends of the several blo pipes 22 may be anchored in any appropriate manner, but they are preferably extended through the walls 18 as clearly shown in Figs. 2 and 4, the ends of said pipes being closed by caps or the like 22, which caps can be removed when it is necessary to clean the blow pipes. This construction is likewise an advantageous feature of the invention, since it will be evident that a flue cleaner or the like may be forced through the pipes 22 without coming in contact with any other parts of the forge. This allowssaid pipes to be more readily cleaned than would be possible by disposing them in a manner otherwise than that described and disclosed in the drawings.

On the working machine, the fire boxes 21 are each provided with av lining of fire brick or the like which covers the branch pipes 23 and only exposes the perforated upper sides of the blow pipes 22, but for the sake of clearness in the drawings, but one of the fire boxes is shown provided with such lining, the latter being indicated at 27 in the drawings and being so disposed adjacent the side and end walls of said boxes as to constitute a ledge or the like 27 upon which the tools or other bodies to be heated may rest, the inner ends of such bodies being of course projected into the beds of burning fuel built Within the fire boxes.

As will be evident to those skilled in the art to whichthe invention relates, the necessary draft air is furnished to the fire through the pipes 24, 23, 23 and 22, while the smoke from the fire may be allowed to rise in a suitable hood 28 through a flue 29 in the top thereof, or may be drawn downwardly within the flue 11 and the hollow post 2 by suction created therein by any preferred type of suction fan F having a suction pipe P communicating with the interior of said hollow post, (see Figs. 1 and 6)). If the last-named method be adopted for discharging smoke from the forge, the funnel shaped inlet member 30 is preferably though not neeessarily' provided at the' uppe r end of the flue 11, said member 30 being shown in the present application as provided with a depending annular fiange 30 which is received by the open upper end of said flue. I

The hood 28 above described may be of any preferred design for accomplishing the best results, but it is preferably of a shape corresponding to that of the pan 9, having upright walls 18 disposed above the walls 18, and shorter walls 18" rising from the walls'18 all of the wa1ls18 being provided with an angle iron flange 19 which projects outwardly therefrom and rests on the angle iron 19 previously described.

Bolts or the like 31 are then passed through the two angle irons to rigidly secure the hood 28 in position upon the pan.

It is necessary to provide the walls 18 of the hood 28 with suitable openings whereby tools or the like may be inserted therethrough into the several fire boxes 21, and

Within the several fire boxes, removal of thetools from which, to be acted upon by the sharpening means, is facilitated by the fact that the pan 9 can be rotated, thus allowing any desired fire box 21 to be disposed adjacent said means.

I have found that the machine works to great advantage for the purpose above set forth, but it will be evident that the application of the invention need not be restricted to such use. Furthermore, although certain specific details of construction are shown in the accompanying drawings and described in the preceding, it will be evident that I need not be limited thereto otherwise than to the extent to which the appended claims restrict me.

I claim:

1. In combination, a hollow rigid post capable of serving as a smoke flue, a pan member rotatably supported thereby and including a plurality of fire boxes, an upright rigid blast pipe in the post, an additional and rotatable blast pipe rising from the rigid pipe, and branch pipes leading from the additional blast pipe into the several fire boxes.

2. In combination, an upright hollow post, a pan member rotatably supported thereby and having an opening at its center, a tubular flue rising from the pan member and surrounding the opening therein,

3. In combination, an upright hollow post in which suction is to be created, a pan member supported by said post and having a. central aperture opening into the same, an upright flue rising from the pan member and surrounding the aperture therein, av funnel-shaped entrance member disposed at the upper end of said flue, and a hood rising from the pan member and confining the flue and the entrance member therein.

l. In combination, a rotatable pan member, an upright flue member rising from the center thereof and in which suction is to be created, partitions radiating from the flue member and dividing the pan member into a plurality of fire boxes, and a hood rising from the pan member and disposed above the partitions and flue member.
